Definitions

• the invention relates to a method for the automatic transfer of garments to folding machines with the associated device, and a transport bracket with the features in the preambles of the main device and method claims.
• Such a transfer device and such a transport bracket are known from GB-PS 1 314 168.
• the items of clothing hanging on the transport brackets are moved along a horizontal conveyor line by means of hooks and placed on the sloping work surface of the folding machine.
• the items of clothing are held on the work surface by suction pressure, while the transport brackets are moved in the horizontal direction and are pulled out of the items of clothing.
• This has the disadvantage that the transport bracket is bent during this movement, which affects its functionality and also leads to undesirable wrinkles on the item of clothing.
• the transport brackets used have the further disadvantage that they are mechanically unstable and have a complicated locking device. This means that the bracket arms can only be folded down with great effort and raised again for a new loading.
• the invention solves this problem with the characterizing features in the main method and device claim and the secondary claim for the transport bracket.
• the bracket With the pull-out movement of the transport bracket according to the invention in the direction of the work surface inclination, the bracket is prevented from bending.
• the folding movement of the bow arms and the pull-out movement run in the same plane, so that the bow can be pulled out without folds and damage to the item of clothing.
• the transport bracket is therefore also mechanically loaded to a lesser extent.
• the transfer device has in its conveying device a climbing path that deviates from the normal transport direction and is arranged in such a way that the bracket can only be placed flat with the item of clothing onto the working surface of the folding machine and then pulled off in the direction thereof.
• the conveyor device according to the invention can be an integrated component of a superordinate conveyor line with which different treatment stations are connected to one another.
• the invention prefers an independent conveyor device assigned to the individual folding machine. For a higher degree of automation, this can be connected to external conveyor lines for the loaded and unloaded transport brackets.
• the independence of the conveyor device according to the invention has the advantage that several folding machines on a higher-level conveyor line can be connected via switches and the like.
• the climbing route can be realized more easily and the folding machine can be decoupled from the work cycle of the other machines in an automated laundry system.
• the conveying device is designed as a chain drive, preferably rotating in a triangle, with a plurality of drivers for the transport bracket.
• loaded transport brackets can be taken over on the input side at the same time, the clothing items can be folded down in the central area and the empty transport brackets can be removed again on the output side. It is controlled by several contactless sensors that register and report the position and movement of the drivers.
• the transfer device according to the invention also includes a suction device for holding the item of clothing on the work surface, for pulling out the bracket and for subsequent longitudinal folding.
• the suction device according to the invention can be controlled in its pressure level.
• a lower suction pressure is set to pull off the bracket than with the longitudinal fold.
• the low suction pressure holds the garment in place, especially on its underside, and prevents it from slipping when the bracket is pulled out.
• the top of the garment is held in place by the low suction pressure with only a small force.
• the hanger can thus fold in between the sides of the garment without hindrance and also does not lead to a distortion of the garment.
• the transport bracket according to the invention has bracket arms with only two pivot bearings.
• the bow arms are designed as spreading springs and have closed bow tips for this purpose.
• the spring effect causes the housing to be moved when the stirrup is pulled off, as a result of which the housing movement and the pivoting movement of the stirrup arms overlap with one another in such a way that the stirrup slips out of the item of clothing without folds.
• the bracket arms are first folded down without this movement overlay, and only then is the bracket pulled out of the item of clothing. However, the folding movement causes warping and wrinkling on the item of clothing.
• the spring effect also stabilizes the loaded transport bracket and allows it to unfold automatically. The latter reduces the effort required to fully automate the entire laundry system.
• the transport bracket according to the invention shows its advantages especially in cooperation with the transfer device and the method according to the invention.
• the combination results in an optimal solution to the task.
• the transport bracket can also be used successfully in conjunction with others, for example the previously known one
• Transfer device can be used. Likewise, the transfer device according to the invention can also cooperate with other transport brackets.
• bracket arm bearings results in a dead center position, after which the pivoted bracket arms are fixed in their position. To open it, only a small insertion movement of the Bow hook with the backdrop, whereby the dead center position is exceeded and the bracket arms open automatically.
• the transport bracket with the resilient bracket arms stabilizes itself in the opened position and therefore does not actually require any locking. In modern tunnel finishers, they can
• a lock in the form of a locking lug can additionally be provided on the resilient free end of the bent bow hook lower part.
• the locking nose according to the invention is released with a simple evasive movement of the free bottom end. This happens automatically when the transport bracket is pulled out, the free end being moved and deflected with a guide bevel against a briefly protruding unlocking bolt.
• the stirrups are again to be safely delivered on the output side to a subsequent conveyor section. This can be done by letting the bracket slide off the tow hook into a suitable position on the subsequent conveyor line. In practice it has been shown that this is not sufficiently reliable. The stirrups can get stuck or even fall off during handover. Another problem is the fact that the transfer speed of the towing hook is limited by this transfer, which is reflected in the cycle time of the folding machine. In this context, a geometrically simple shape of the towing hooks has also proven to be unfavorable, since the transfer and delivery of the brackets to and from the subsequent conveyor lines does not work with certainty. In addition, when the bow arms are folded in, a sudden upward movement of the bow can occur, whereby the bow disengages from the drag hook.
• the items to be folded are in a treatment line at the docking station with the button facing upwards, i.e. turned to the operator.
• the garments maintain this orientation during their passage through the various treatment stations, such as finishers and the like.
• the items of clothing must be in the upside-down position, i.e. H. be fed to the work surface of the folding machine with the button bar.
• Another problem is the transfer of the hangers with the items of clothing from the incoming conveyor line to the transfer device on the folding machine. This can lead to malfunctions due to falling hangers and clothing.
• the main task therefore has the additional aspect of also improving the operational safety of the transport devices and, in particular, of ensuring the safe transfer of the brackets.
• a transfer device for the transfer of the empty brackets in the region of the inclined rise section of the conveying device, which removes the brackets from the drag hook in an active and defined movement and allows them to slide safely onto the subsequent conveying section.
• the device according to the invention can also be used successfully use other laundry machines and other other transfer points in the transport system of a laundry.
• the ironing device has a stop block that brings the lifted bracket into a defined position at the end of the movement and centers it there, so that the bracket will slide with certainty on the subsequent conveying path. It is advisable to arrange the stop block at the end of the climb, as the reverse movement of the towing hook can be used here.
• the linear actuator lifts the bracket from the drag hook and forcibly guides it through the sloping position and its guide plate to the stop block.
• the bracket can be spread out again when the thrust drive is correspondingly large during lifting.
• the device according to the invention is also suitable for any other bracket shapes and thus also for rigid brackets for which the stroke is correspondingly shorter.
• the drag hooks In order to ensure the transport of the stirrups in the transfer device on the folding machine or another laundry machine and also to facilitate the function of the ironing device, the drag hooks have a spiral shape and are rotationally connected to the links of the conveyor device. As a result, the tow hook rotates at the functionally important positions, such as the pick-up and transfer points to the subsequent conveying sections and at the beginning of the climbing section, in which the hanger is folded in and pulled out of the ready-to-fold garment.
• the rotary movement in connection with the special design ensures that the bracket slides securely on the tow hook at the pick-up and transfer points, or released by this.
• the engagement with the bracket is ensured, even if the bracket makes a sudden upward movement when its arms are folded in.
• the engagement is also secured on the horizontal and inclined (ascending) transport routes, so that the bracket cannot slide off the tow hook due to rocking movements or other external influences.
• the towing hook has an eye with a narrow access opening, which only releases the hanger suspended in it in certain rotational positions of the towing hook.
• the above holding arm offers a defined sliding surface for receiving and transferring the bracket, which guides the bracket into the desired position.
• the holding arm also has a locking lug. This also offers additional security against falling of the bracket in the event that it slips out of the eye due to extreme external influences on the transport routes.
• the design of the towing hook is for the conveyor device according to the invention.

• it also lends itself to use on other conveyor devices in the area of a laundry, for example also at other treatment stations, folding machines according to the prior art or the like.
• a bracket converter in the form of a multi-armed driven turnstile is arranged. This also allows the garments to be rotated, so that the button strip points towards the contact surface of the folding machine. In this sense, the strap converter according to the invention can also be used elsewhere can be used in a laundry conveyor system.
• the turnstile is aligned with its arms at an angle to the conveyor and the upstream conveyor line.
• the inclined position ensures that the conveyor line slides onto the turnstile, while, after the rotation has been completed, the bracket can slide obliquely to the conveyor device.
• the upward and downward sliding movements of the rotating and thus moving conveyors are additionally secured by guide elements.
